edtFTPj/PRO is a Java library that performs secure file transfers. It supports FTPS (FTP over SSL), both explicit and implicit modes, and SFTP (FTP via SSH). It also supports asynchronous transfers and FTP connection pools. All major FTP operations are supported, including both active and passive modes. It provides a progress monitor interface, allowing applications to receive progress updates for their file transfers. The library is built on the open source edtFTPj and shares its API. It is compatible with Android 1.5 and above.

Password Manager Daemon serves clients data via a Unix domain socket or over a remote TLS connection. The data is stored in an (optionally) encrypted XML file, and the client must provide the key to modify it. It has the option to use gpg-agent for key management (including smartcards). It is multi-threaded, allowing more than one client to be connected at the same time. Key retrieval may be done via a key file or a pinentry program. A key cache is used, so a client won't need to enter a passphrase each time one is required. It is very configurable. Libpwmd is also available as a separate project and is a library making it easy for applications to use Pwmd.

SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing and chat services. It can be used to send any kind of messages, in addition to normal text messages, including multimedia messages like images, video, and audio stream. All messages in the SILC network are encrypted and authenticated, and messages can also be digitally signed. SILC protocol supports AES, SHA-1, SHA-2, PKCS#1, PKCS#3, X.509, OpenPGP, and is being developed in the IETF. The software is delivered as SILC Client for end users, SILC Server for system administrators, and SILC Toolkit for application developers.

SaluSafe is an encrypted email, chat, and file storage and sharing system. Your email and files are highly encrypted end-to-end, and cannot be intercepted by any third party. It was built from the ground up for security via strong cryptography, and is not just another security wrapper on top of an existing email solution.

CryptoHeaven offers secure email and online file sharing/storage. Its main features are secure and highly encrypted services such as group collaboration, file sharing, email, online storage, and instant messaging. It integrates multi-user based security into email, instant messaging, and file storage and sharing in one unique package. It provides real time communication for text and data transfers in a multi-user secure environment. The security and usability of CryptoHeaven is well-balanced; even the no-so-technically oriented computer users can enjoy this crypto product with very high level of encryption.

DeleGate is a multi-purpose application level gateway or proxy server that mediates communication of various protocols, applying cache and conversion for mediated data, controlling access from clients, and routing toward servers. It translates protocols between clients and servers, converting between IPv4 and IPv6, applying SSL (TLS) to arbitrary protocols, merging several servers into a single server view with aliasing and filtering. It can be used as a simple origin server for some protocols (HTTP, FTP, and NNTP).

The Mandos system allows computers to have encrypted root file systems and at the same time be capable of remote or unattended reboots. The computers run a small client program in the initial RAM disk environment which will communicate with a server over a network. All network communication is encrypted using TLS. The clients are identified by the server using an OpenPGP key that is unique to each client. The server sends the clients an encrypted password. The encrypted password is decrypted by the clients using the same OpenPGP key, and the password is then used to unlock the root file system.
